9 Claims.

This invention relates to improvementsin machines for immersing materials such as yarn, cloth or the like in dyeing solutions and working the same therethroug'h to effect the dyeing thereof. f

The primary object of the present invention is to provide a machine by means of which the material .to be dyed is held submerged in and worked back and forth through the dyeing solution so that intimate contact of the solution with all of the fibers of the material is attained and an even dyeing of the material results."

Another object of the invention is to provide a machine of a character to handle material in the'form of yarn or finished woven articles such as stockings or the like, the latter articles being carried in baskets into which the dyeing solution may easilypassfi A still further object of the invention is to provide a machine having a novel means for maintaining the yarn carrying members and the article carrying baskets in a fixed upright po si-- tion while moving the same through the dyeing solution. p

A still further object of the invention is to provide a machine of the above described character in which the members carrying the material to be dyed are moved along an endless path in the dyeing vat'so as to create a circulation of the dyeing fluid through and about the strands and fibers of the'material being dyed.

Still another object of the invention is to provide a dyeing machine in which the mechanism may becompletely removed as a unit from the dyeing vat for loading or unloading the material carrying elements or for effecting any necessary repairs inthe structure;

The'invention also has for an object the provision of a novel means for locking yarn carrying frames and baskets to an endless chain bywhich they are moved through the dyeing solution.

Other objects and advantages of the invention will become apparent as the description of the same proceeds and the invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawings but may be changed or modified so long as such changes'or modifications mark no material de parture from the salient features of the invention as expressed in the appended claims.

Figure 11 is a sectional view taken on the line 11-11 of Figure 12;

Figure 12 is a'view in side elevation of a portion of the center guide with which the yarn frames and baskets slidably connect Referring now more particularly to the drawings wherein like numerals of reference indicate corresponding parts throughout the several views, the numeral 1 indicates generally a tank or vat in which .the dyeing solution is placed, filling the vat to the height indicated by the broken line 2. Extending across the top of this vat and supported by the side walls thereof are the two platforms 3'and 4 each of which has secured thereto adjacent each end an eye or loop 5 by means of which a hoisting mechanism may be connected with the platforms and the hereinafter described structure attached thereto for lifting the mechanism of the machine from the vat.

Mountedluponthe platform 3 is an electric motor 6, the armature shaft 7 of which carries a worm 8 which meshes with a worm wheel or gear 9 which is supported upon a shaft 10 extending longitudinally of the platform 3 and mounted at its ends in the bearing brackets 11. At each end this shaft 10 carries a sprocket gear 12' h v V Extending downwardly into the vat 1 from each end of each of the platforms 3 and 4 is a hanger 13 in the lower end of which is a suitable bearing 14 of the thrust type. Mounted in the bearings of the two hangers carried by each platform is a shaft 15 which extends across the tank 1 as illustrated. These shafts are prevented from transverse movement in the tank because of the nature of the bearings 14 in which their ends are mounted.

The shaft 15 lying beneath the platform 3 has mounted thereon adjacent each end, the relatively large sprocket gear 16 which is coupled by means of a suitable sprocket chain '17 with the overlying sprocket gear 12. By this means the shaft 15 is driven or rotated by the motor 6.

Adjacent each end of each of the shafts 15 there is mounted thereon the large sprocket wheel 18 and the sprocket wheels upon one shaft 15 are connected with the adjacent sprocket wheels upon the other shaft 15 by means of the endless chains which are indicated generally by the numerals 19.

These endless chains 19 are of special construction as is shown in Figures 7 and 8 where as will be seen, each of the links is made up of two elongated plates 20 which at one end receive therebetween the ends of an adjacent pair of plates and at the other end are received between an adjacent pair of plates and connection is effected between the'ends of the plates 26 of one of the links and the ends of the plates of an adjacent link by means of a pin 21 on'which is mounted between the plates the cylinder 22 which serves both as a spacer for the plates of the links and as a supporting roller for the chain as will be hereinafter more fully described. This member will be referred to hereinafter as the A roller of the sprocket wheel chain. 35

the numeral 23 in Figure 10, have the side plates provided at their top edges with the spaced upstanding cars 24' and at one side of these ears there is hingedly attached to the links by means of the pin 25 and ears 25, the bar 26 which is designed to extend longitudinally of the link to the opposite side of the ears 24 and be secured at its other end to the link by means of the thumb screw 27, This bar 26 carries upon its top side the transversely extending roller 23, the purpose of which will be hereinafter more fully explained.

Mounted between the shafts15 and supported thereby to extend longitudinally of the dyeing tank are two planks each of which is indicated by the numeral 29 which have their ends rounded as shown in Figure 1 and their inner or adjacentcorners cut out to form the grooves 30.

, The outer sidesof these grooves are closed by 55 the band 31 which surrounds the edge of each plank 29, thus forming each groove with one open side only which is directed toward the groove of the opposite plank. At one point along the top edge of eachplank the band 31 is broken to form the opening '32 and this opening is normally closed'by the bar 33 which is hinged at one end as indicated at 34 to the band and extends across the opening'and has its other end detachably secured to the band by means of the thumb r the tank thus slidably supports the adjacent run of a chain 19 to preventthesame from sagging. In the bottom of the tank beneath each chain is a metal track 38 which extends longitudinally of the tank and along which the rollers 28 of the members 26 move should the chain sag in passing along the bottom run.

The numeral 38 indicates generally a frame designed to carry yarn or similar unfinished material through the dyeing tank and at each end of this frame which is of elongated rectangular design, the side bars" are extended to form the pins 39. Between the end bars 40 of the frame is oscillatably mounted upon the trunnions 41 the elongated rectangular oscillatory frame 42.

The numeral43 indicates generally a receptacle formed of a suitable foraminous material and as shownthis receptacle in cross section is of greaterwidth adjacent one longitudinal edge than at the other and in the longitudinal edge of greatest width there is provided a door 44 through which articles may be introduced thereinto.

,At each end of the receptacle 43 and adjacent each longitudinal edge is a trunnion 45 which extends longitudinally of the receptacle as shown.

In the use of the present machine where formed articles or unfinished woven, material is to be dyed, the receptacles43 are employed, and for yarn or other thread the frames 38 are employed. In order to attach the receptacles and frames to the sprocket wheel chains 19 by which they are moved throughthe tank, the entire mechanism is hoisted from the tank by lifting the platforms 3 and 4 in the manner previously described and the receptacles and frames are disposed transversely of the chains" 19 with the end trunnions adjacent one longitudinal edge engaged in the opposed guide grooves 30 and the trunnions adjacent the other longitudinal edge each securedbetween a pair of cars 24 by means of the adjacent securing bar 26.

It will, of course,.be readily understood that the trunnions first mentioned are inserted in the guide grooves 30. of the central members 29. by shifting the bar 33 so as to permit the trunnions to be slipped into the grooves through the opening 32. i h

After the frames and receptacles have been mounted between the carrier chains 19 the mechanism is again lowered into the tank and the motor 6 started to cause the frames and receptacles to be carried back and forth along a continuous path in the manner illustrated in Figure 2.

. In order that the dye fluid in the tank 1 may be prevented from circulating with the moving frames and receptacles there is disposed in each end of the receptacle andtransversely thereof the obliquely directed apertured baffle plate 46.

. This hinders the circulation of the fluid to a certain extent so that the penetration of the dye fluid into the articles and material to be dyed will be more thorough.

In applying the yarnor other thread-like material to the frames 38 the oscillatable frames 42 are disposed in the same plane as the main frame until after the yarn has been wrapped thereabout after which these oscillatable frames are swung to extend substantially transversely of the main frame and thus stretch the yarn threads and hold them in taut condition.

From the foregoing it will be readily apparent that the frames and receptacles, being attached adjacent one side to the carrier chains 19 and adjacent their opposite sides or edges to the endless center guide groove or track 30, will be carried through the dye vat in such a position that the 1.
